Kennebunk Beach Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what’s on the cards for our local stretch.

First off, Kennebunk Beach (Kennebunk-Beach) is a sheltered little nook, so it doesn’t grab every swell that rolls through the Gulf of Maine. That means our 16-day forecast starts with a real flat spell. We’re looking at a dry run from the 27th of August through to the 6th of September. That’s over a week of pretty much nothing worth paddling out for. The water’s sitting at 66°, which is a touch warmer than normal for this time of year – not a bad thing if you’re just floating around, but there’s no wave to float on.

Things finally start to stir on the Sunday morning of the 6th of September. We get a pulse of easterly swell at 3ft and a 9-second period, with light offshore winds from the north-east. It’s clean, but the wave energy is still pretty modest at 152 (moderate energy). It’s a surfer’s wave, but nothing to get emotional about. Monday the 7th of September morning looks a bit dicey with stronger cross-offshore winds, but the afternoon cleans up again with a moderate offshore breeze and similar 3ft swell from the east-southeast. Still just ordinary conditions, though.

Now, if you’ve got some patience, the real standout window opens up around the 8th of September. We start seeing a longer-period groundswell kicking in from the south-east. On the morning of Tuesday the 8th, we get a 14-second period, but it’s a little small at 1ft – it’ll be super clean with a solid offshore wind, though. The energy is still building at that point. The highlight looks to be Wednesday the 9th of September and Thursday the 10th of September. We’ve got a clean 2ft to 3ft south-east swell, with a 12-second period bringing some real shape and power, and the combined energy is sitting around 153 to 160 (moderate energy). The winds are either glassy or light offshore, so the surface will be silky.

For a spot like Kennebunk Beach that’s sheltered from the east-northeast, this south-east flow is the best we can ask for. The long period means the waves will have some push, but on a beach break like this, they might run a bit straight. Still, if you’re lining up for a session, the Wednesday morning (9th September) with that 2ft, 12-second groundswell and gentle offshore breeze is the pick of the bunch. It’s not huge, but it’s clean and consistent.

After that, the swell drops and the winds turn onshore again. The following Friday (11th September) sees a bigger bump in energy, hitting 296 (moderate energy) and then 279, but the swell is short-period (6 to 7 seconds) and the wind is onshore – that’s just a choppy mess.

To be straight with you, overall, this is a long wait for a few days of okay surf. The best bet is that Wednesday the 9th of September session. It’s not a classic, but it’s the only genuine window with clean, long-period lines on offer.
